Turbidity EPA 180.1

Analytes

Turbidity


Summary

The method is based upon a comparison of the intensity of light scattered by the sample under defined conditions with the intensity of light scattered by a standard reference suspension. The higher the intensity of scattered light, the higher the turbidity. Readings, in NTU’s, are made in a nephelometer designed according to specifications outlined in the method. A standard suspension (i.e., formazin, AMCO-AEPA-1, or Hach Stablcal) is used to calibrate the instrument.
